Template:Interlanguagelink: en The Has preferred property label property is a special property in Semantic MediaWiki with a built-in meaning: it adds the possibility to localize the label of a property. It was introduced starting with Semantic MediaWiki 2.5.0.1

With the introduction of the "Monolingual text" datatype, Semantic MediaWiki is able to provide a method to denote a text element of arbitrary length with a language tag thus allowing it to distinguish such text by the same attribute.

Adding preferred labels to a property specification is aimed at increasing the likelihood for a user to understand the concept of a particular property by defining a label in a language (as side from the canonical label) a user is most familiar with.

Features and limitations

• Borrowing on the "skos:prefLabel"2 definition, the preferred label is understood as to only have one label per given language (while "skos:altLabel"3 can have many alternative labels but this is not part this issue)
• To separate a canonical label from a preferred label during the output, a small ^p hint will be shown along with the label
• The preferred label feature is aimed for the output and not for the annotation process, meaning that a reverse matching during an annotation process is not supported ([[Has population::123]] vs [[人口@ja::123]], annotations are expected to use the canonical identifier or label)
• The user language is being used as selective attribute that will trigger a change of labels, if available
• Can easily be combined with the property link feature4 ([[SomeProperty::@@@]] or [[SomeProperty::@@@en]]) to create local-specific infoboxes.

Example

On the "Has population" property page in namespace "Property" one would add the following to define preferred property labels for the the languages specified language French (fr), German (de), Japanese (ja) and Spanisch (es):

* [[Has preferred property label::population@fr]]
* [[Has preferred property label::Bevölkerung@de]]
* [[Has preferred property label::人口@ja]]
* [[Has preferred property label::población@es]]
